Importance of Superphosphate

In the industrialized countries of the World the production of superphosphate has been declining for some time, because, with a P205-content of only 19 to 20%, a very high proportion of ballast has to be transported with it. In addition the biological availability of the phosphorus is lower than with other fertilizers. Superphosphate is still important in China and Eastern Europe. The world production by regions in 1994 is given in Table 2.1-4.
